Description
The Irwin 11/64″ Carded Cobalt 135 Degree Jobber Drill Bit (3016011) is a high-performance tool engineered for drilling through the most demanding materials. Constructed from high-speed steel with a 5% cobalt alloy (M35 Grade), this bit provides exceptional heat and abrasion resistance. Its 135-degree split point is a standout feature, designed to eliminate bit walking and ensure a precise, immediate start. This bit is ideal for tackling tough metals like cast iron, stainless steel, and hardened steel, making it a reliable choice for professionals and serious hobbyists alike. The heavy-duty web construction adds significant strength and longevity to the tool, ensuring it can withstand repeated use in rigorous applications. With a gold oxide finish, it also offers added corrosion resistance and reduced friction. This is a single, carded bit that is ready to be used for your next challenging drilling project.
KEY FEATURES AND BENEFITS:
- M-35 Cobalt Construction: The bit is fortified with a 5% cobalt alloy, which significantly enhances its ability to resist heat and abrasion, allowing it to maintain its sharpness longer when drilling through hard materials.
- 135-Degree Split Point: This point design prevents the bit from “walking” or skidding across the material’s surface, enabling a precise, clean start with minimal pressure.
- Heavy-Duty Web Construction: The bit’s design includes a reinforced web, providing greater strength and stability, which helps prevent breakage during high-stress drilling tasks.
- Versatile Application: Specifically engineered to perform effectively on tough materials such as cast iron, stainless steel, hardened steel, and other abrasive alloys.
- Gold Oxide Finish: This finish reduces friction and provides an extra layer of protection against rust and corrosion, extending the bit’s lifespan.

HOW TO USE:
- Select the Right Drill: Ensure you are using a drill that is suitable for the material you are working on. For hard metals, a powerful drill press or a high-torque handheld drill is recommended.
- Secure the Workpiece: Use a clamp or vise to securely hold the material you are drilling. This prevents movement and ensures a safe, accurate hole.
- Install the Bit: Insert the 11/64″ bit into the drill chuck and tighten it securely. Make sure it is centered and not wobbling.
- Start Drilling: Begin drilling at a low speed to create an initial indentation. As the bit bites into the material, you can increase the speed gradually.
- Apply Lubricant: For drilling tough metals, it’s crucial to use a cutting lubricant or coolant. Apply a small amount to the drill area to reduce heat and extend the bit’s life.
- Maintain Steady Pressure: Apply consistent, firm pressure to the drill. Avoid excessive force, which can cause the bit to overheat or break.
- Clean the Hole: Periodically withdraw the bit to clear chips and debris from the hole, especially when drilling deep holes.
